Honestly, I don't know... I was considering one of those before I got mine, opted for the generic OUKU for a few reasons:

- It's the most discussed, hacked

- Silly I know, but I like the idea of a knob for volume

- The motorized face is just something else that's bound to fail IMO

I just tried to find some reviews on youtube, couldn't see any with that OS on that model. It has a different looking (some of it better looking) interface than these, rooting with roms discussed here would change that if it was even possible. If you can find a picture of the system info/versions (or a video that shows it) that would help. If you decide to get it, the best option would be for you to REQUIRE as part of the deal for them to include a copy of a full recovery ROM either as a download or on the card "for peace of mind" I wouldn't doubt it would be rootable with it....

Then again, maybe someone who owns one chan chime in?
[Android Head-Units] RealMayo:
Have any of you guys tried installing Swype on this? Does it work?

I bet it wouldn't work so well on a resistive screen.
[Android Head-Units] jakejm79:
I saw your link, could you confirm exactly which one you received, looks like there are 3 pictured in the ebay listing two Ouku looking units that near identical but the hard buttons are labelled a little differently, then something completely different under the picture for the touchscreen portion of the listing, also in the details at the end it shows resistive for the screen type.

I am considering this one: http://www.ebay.com/itm/151158301958?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I've contacted the seller and he claims it is capacitive, also all the pictures seem to match throughout the listing. I've added the seller to skype, just trying to get a time when we are both awake so he can demo it, I will have him show what MCU version is on it when I do get a hold of him.

Good to know on the ipod SW controls, shame there is no widget for the ipod app tho. I'd like to be able to see all my music info that is playing while on the home screen, but maintain steering wheel controls.

Lastly the one I linked above appears to support OBDII via BT and comes with 2.3.7. I'm wondering if it comes preloaded with one of Hal9K's roms, I doubt that the built in BT supports it, but they may mean that a separate BT dongle would.

Anyway if I can confirm that everything listed checks out I will probably take the plunge.
[Android Head-Units] sciallo:
Looks like it's exactly like the one I got, These guys have the tendency to copy/paste their listings and sometime miss things... I asked and confirmed before buying it. In fact a couple of listings said capacitive in the title and resistive in the description and when asked they told me it was resistive... I didn't even try to see if the new firmware supports odb, they might have added support for BT dongle in their newer version, I'll try once I get mine back to stock... I think the two are exactly the same unit but yeah, due diligence, ask... Personally I prefer shipping included, that way if I need to return they refund the whole price (I might have to pay to ship back), if you pay for shipping refund would only be on the purchase price... Not that you will return it... :p
[Android Head-Units] jakejm79:
Ok so your unit has Home Menu Back and Navi on the left and then Radio >> << and Phone for the hard buttons on the right?

I think either way I would never ship it back or return it so it makes little difference, I would rather get the one I can have demoed to me.
[Android Head-Units] RealMayo:
If you're brave enough to venture away from eBay and instead deal directly with the Chinese manufacturers, then this is a great resource... it searches all Chinese manufacturers for what you want...

They've got nice peripheral trim that matches whatever car you have.

For example I'm thinking about getting this one.... (Can somebody please mouse over all the screenshots of this particular one and tell me if it looks legit to you?)....

Check also aliexpress. Alibaba is mostly for buying and reselling they expects you buy an entire lot. Even if some manufacturers will sell you "1 unit" payment options and shipping cost may not be very attractive. Many will have a shop on aliexpress also. I always check first aliexpress, but I was also able to buy some years ago a PNA from alibaba (it's the same company in fact) before they created aliexpress.
[Android Head-Units] sciallo:
Yeap, well from top to bottom , << then >> to be precise also, left of the dvd slot it's "DVD", not the power symbol, and volume knob is on the left, not on the right as opposed to what the posting pic shows.... I believe that picture is of a cheap wince unit...
[Android Head-Units] RealMayo:
So I might have got screwed by trying to purchase from aliexpress.com

I attempted to buy this one...

click here

I entered my credit card and submitted the order.

Then later I got an email from this seller saying "Sorry, this item actually doesn't exist"

Are you @!#$! kidding me?!

So no my order is in limbo with a status of "Verifying Payment"

Hopefully I come out of this one with out getting screwed :(
[Android Head-Units] sciallo:
I'm sure they won't charge your card if they're not selling you the unit, though it might lock that amount as pending for a few days... I noticed it sais

I guess you should have done that even if you don't need options...

Check your bank account, contact them and if the transaction goes to completed on your statement, reverse the charges with your bank.
[Android Head-Units] Decapper:
If you get charged, just ring your bank and get a charge back
[Android Head-Units] hmosquera:
I put the hal9k´s MCU, and the MCU downgrade...... but i don´t have any problems with the sound in my unit.
[Android Head-Units] KID52:
There is no need to worry, honestly. There is also no need to contact your bank for a chargeback. Aliexpress acts as an Escrow, so your payment never goes to the seller until you confirm delivery of the order.

Payment can take a couple days to verify, once this happens I would expect the seller to refund you immediately - make sure to send them a message stating you want the refund as there is no product.

Give them some time to issue the refund - 48 hours is fair. It will not appear in your account immediately, this may take up to 10 days.

If the seller fails to provide a refund, open a dispute for a full refund and state what has happened.

If the seller still rejects this, raise the dispute to customer services (there will be an option in the dispute for this). You will receive your refund within 30 days.
[Android Head-Units] sciallo:
Well, that leaves me baffled. I guess restoring MCU whenever I get it will not fix my problem... Thanks so much for the info.

This is driving me insane, I think something told the amp portion of the unit to route the sound elsewhere or mute it, and nothing told it to turn it back. What's been driving me crazier is that NOTHING seems to reset the firmwares settings. Abunch of settings like tv mode, radio region etc.... For example, I renamed my phone's BT "expy BT" and nothing I do changes that. Reflash, restore to default, Diconnect all power overnight, reset...

"Expy BT" is still there, and so are many other settings, so I wonder if a "stay quiet" internal invisible magic setting is there too.

I do hear button press beeps out of the speakers, so I guess the amp/sound system is not blown.... Going crazy, we'll see what the Chinese reccomend... If anyone has ever opened the unit, did you see any small memory type battery in it (motherboard's eprom like) maybe? ...not ready to void the warranty yet or I'd look for myself.
[Android Head-Units] Decapper:
I think I seen someone on here say Winamp muted them.. Try installing Winamp andmute unmute maybe.

Also read on another forum that the audio is independent and ppl wanting to start program's at boot can't due to the fact that you have to boot a audio program like radio or music beforehand to get sound.. Maybe related?
[Android Head-Units] RealMayo:
FYI I decided to contact a different seller on aliexpress and ask them if the item they are advertising is actually in stock. They replied no. LOL WTF!
[Android Head-Units] sciallo:
I will try winamp.

I am sure it's related, something I did muted the sound for good... Problem is I don't know what, and whatever I do hasn't brought it back. You would think a full reset to defaults would bring everything back to normal...

Internal apps such as built in music player are "priming" sounds as I read, If I enable a sound activated background like the vu-meter, it responds to it, still I hear nothing... I will also try redirecting sound to a bluetooth speaker, and see if I get sound out of it, then maybe disabling that will bring it back? I tried sending sound through the phone's bluetooth still nothing.

I'm trying all I can think of, but please keep some suggestions coming...

Pure 4.1 android

Hi guys,

I've been looking through the thread to see if this unit can be rooted. It is a pure android 4.1 listed by Peter Chan. I will buy this and report back if this is indeed rootable.

The ebay page Peter Chan has listed is

ebay.co.uk/itm/Capacitive-Touch-Screen-Android-4-1-Car-Radio-Stereo-GPS-DVD-BT-USB-3G-WIFI-TV-/181257888801
[Android Head-Units] KID52:
The link does not seem to work.

I will assume it is the same unit I have, unfortunately I have not been able to root it so far.

I have tried the latest version of Framaroot, which did not work.

I have also obtained the system image, linked a few posts back, but it appears to be encrypted, so I cannot alter the files to try and root the device.

Hopefully you will have better luck than I did.
[Android Head-Units] chris.r.r:
We should contact Hal9k_. I assume that it could work the same way as for the OUKO 2.3.x model. Or is the old 2.3 firmware not encrypted?
[Android Head-Units] sciallo:
Do we know it's in fact encrypted? it seems like the filenames are just some sort of checksum, but that doesn't mean they're encrypted necessarily... Did anyone try to mount them? I might give it a try later as I'm starting to think I'll have to return mine, If the 4.1 is rootable I might go for that instead...
[Android Head-Units] KID52:
Pretty sure they are encrypted as well as the hashed names.

The unit somehow detects these names and uses them when you go to system update in the settings menu, so there must be some logic to the naming.

I've tried WinRAR (unlikely to work), and Ext4 unpacker, but no luck with either.

I uploaded the files a few posts back, so anyone is welcome to help out.
[Android Head-Units] KonnecXion:
try to put "www." in front of the link I attached. This is because I'm still a newbie poster so XDA refrains me from posting links.

From what I can see, it doesn't look like a OUKU. If you goto youtube and type in 'pure android 4.1 head unit' you should see a demonstration of the unit. (youtu.be/eMFXR8C0KCQ) (Please put in 'http://' in front as I cannot post links as yet)

Yes it doesn't look like the Ouku 2.3, buttons not the same etc, but I still hope that someone can actually root this so we can abandon the version 2.3 (not to mention a lower hardware spec machine).

This is also not the tablet version or the motorized face panel with android installed on top of WINCE. So is this machine the same as yours KID52? I'm going to add pumpkin_cool (aka PeterChan / youtube link poster) on skype and see how we go.
[Android Head-Units] KID52:
Nope, the item has been removed from eBay, the seller has now got two listings for the unit though. It looks to be the same as what Peter Chan is selling through Skype, he does not seem to have an eBay listing yet.

If you search for "pure android 4.1 head unit" on YouTube you will also find my review :)

Correct, pure Android, no Windows CE.
[Android Head-Units] KonnecXion:
Pretty sure you know which one I'm talking about. Yes I do see your video too.

Ok, I got in contact with Peter Chan and he says the factory encrypts the firmware files. That's exactly what you said and now its confirmed. Looks like there won't be a root for this for awhile.

Aside that, I am looking to get Torque Pro installed on this device. I know you need an OBDII to Bluetooth adaptor, but the question is, does it connect with the adaptor if I use the BlueTooth feature froom this device?

So far, I know only the Ouku pure 2.3 android device can do this...
[Android Head-Units] KID52:
Yes, I found the unit after searching eBay.

Bluetooth only works for phone, and bluetooth dongle does not work, so no Torque I am afraid.
[Android Head-Units] jakejm79:
So I got the same one you got (same seller too) so hopefully it is indeed a capacitive screen and I can just use the same firmware that I had (other than the different file for the screen).

If anyone wants a resistive screen Ouku unit, all rooted and setup for USB OBDII let me know. In brand new condition.
[Android Head-Units] Cool82:
Torque

hello, I want to buy a obd connector that works via wifi or bluetooth on 2.3.7 Ouku units with capacitive screen.

And also I want to buy a usb bluetooth or usb wifi to connect the unit to Obd.

What Obd connector is best for these units?.

What wifi or usb connector is the best?

thanks
[Android Head-Units] sciallo:
I'm at a loss, and about ready to figure out how to ship it back to china :(

I've used linux for years, so I'm not new to command line, but I'd say I'm new to hacking android, however this little sound problem is getting me to dig deeper than I have before into android inner-workings

If I could ask a favour to anybody who's sound is working, would you mind sending me the output of a couple of commands in a terminal:

cat /proc/asound/cards

getprop

and

alsa_amixer

(You can send that output to a text file so it's easy to move around, for example

getprop > /sdcard/extsd/getprop.txt

will output to a getprop.txt file on your external card...)

Also do take a look at those files, some interesting things: seems like there is a setprop for backlight and the alsamixer has a bunch of options, one in particular looks like is about mic sensitivity... Of course not hearing anything out of my unit my experimenting tells me very little other than "no dice, you're not getting audio back this easy"
[Android Head-Units] jakejm79:
I'll head out to the car later and get you the output from those commands if no one else has by then.

Do you think that your problem is related to the upgrade of firmware on your unit or something else (did it happen at the exact same time?). I plan on upgrading to Hal9k's latest firmware (2003.6.14) once I get my capacitive version, just don't want to screw anything up.
[Android Head-Units] sciallo:
I appreciate that, I have the same request out on the FT86CLUB forum, I'll let you know if I get it so you don't have to (though it might be interesting to compare a few...

I am starting to think it's something else, just don't know what yet. I talked to someone that started off with high versions of MCU and system and had no problem after downgrading. My honest suggestion is get the latest HAL9K rom, rename the file for capacitive as usual and remove the MCU file from it. That should work just fine and not touch your newer MCU.

Once you're rooted and you start installing stuff, adding peripherals etc., Don't do it like I did, keep some music playing at all times and do one or two things at a time, rebooting now and then and making sure things work, so if something does happen you know what could have caused it.

I honestly can't tell you if it was the upgrade because as soon as I was rooted I started customizing, and it wasn't until hours of fiddling later that I tried unsuccesfully to play a sound.
[Android Head-Units] sciallo:
Wow, thanks

Very little difference there, and certaitly nothing that would effect sound... U saved me some time I would have wasted playing with that :)

To change those values you'd use

alsa_amixer set 'Capture Vol Reduction' 'Reduced by 6dB'

Though first thing I would do is check the output of alsa_amix again in a few different situations (for example with BT connected) to see if anything changes it or any other value. Also the mic gain might be interesting to play with...

These canges will only be temporary, unless you issue

alsa_ctl store

Then (hopefully) they should survive reboot
[Android Head-Units] jakejm79:
:laugh:

Thanks, I will play with those after dinner.
[Android Head-Units] KID52:
It seems the Android 4.1 unit has a model name of "AN-21 U", perhaps this is not the universal name though, internet search shows no results for now.

Today I received another system image, again encrypted, but from a different source than Peter Chan.

I will try the system files on my unit soon to see what differences there are.

Speaking to some sources, it will not be possible to decrypt the files or edit them. I fear this choice may make the unit unpopular with a lot of people due to lack of root, Bluetooth compatibility, and customization.

Hopefully an exploit will be found, and the device can then be rooted, but I do not have high hopes for this.
[Android Head-Units] Brody602:
Hey everyone,

I'm very interested in buying this head unit:

T6229A from TradeSolution.hk, unfortunately I can't post a direct link to the head unit due to my post count.

It says it's Pure android 4.0, is there any possibility of root for this?

Also does anyone know if android On the go is integrated in these units?

If I can use a USB ELM327 adapter, to use the Torque Pro app, without needing to root, I'd be more then happy without a root, thanks in advance for any help.
[Android Head-Units] chris.r.r:
Yes, I totally agree. In my opionion it's not a very wise decision to prevent users from rooting. This makes the unit uninteresting and many potential buyers will refrain from purchase due to this fact. Moreover, it's very seldom that people destroy their unit completely because of special actions on a rooted device.

Very annoying, but I won't buy one if it's not rootable. This makes the 2.3 unit much more attractive again.
[Android Head-Units] peterchan2013:
it is me :) ,Peter , I ask the factory,you can pay extra cost ,then we can ask factory to add the bluetooth function for OBD2( include the

OBD2 adaptor . ) so ,you can use the Torque.
[Android Head-Units] sciallo:
Indeed, same here, that makes it very uninteresting to me. I am still not too convinced it's encrypted per se. It might just be a different filesystem as it's been suggested elsewhere. Also I was reading that with some the first chunk needs to be stripped off the image. It would be nice if someone who knows this stuff in depth could take a look...

Also, I ran into this:

or this

Maybe worth a try? (I don't have windows, and am dealing with my sound problem but I might find the linux-way counterpart and try when it comes time to deciding to return it in exchange for another 2.3 or the 4.1 ...

---------- Post added at 11:04 AM ---------- Previous post was at 10:49 AM ----------

Still not interesting enough, I want to be able to run apps that require root. I like to be in control of the device I buy and make the best of its potential. The manufacturer should surely understand that by giving that possibility they get lots of people making their device better for free... look at what's been done and what has been fixed on the original 2.3 since introduction... stock it had some serious limitations, most of wich have been overcome thanks to the root being available...
[Android Head-Units] KID52:
But why would I want to pay yet another $50 (price quoted by factory) to add something that I may already have, or that only costs me $10 to buy? By this I mean, I already have a Bluetooth OBD adapter, and many Bluetooth dongles.

It is much better to just allow modification of the firmware, or at the very least, release a rooted version.

Although the unit is okay, it is greatly held back by the lack of community modification potential.

I have already mentioned to you on Skype some minor things which should be addressed, but will these ever be sorted? Probably not.

We've seen how fast the community can react and release alterations, but a Chinese factory listening to customers? Sorry, but it is not something I put much faith in.

I do feel that sales of the new 4.1 unit will suffer, yes the hardware is better, but does that really make up for the complete lack of customization?

Think of it this way, no one is going to want to go from their 2.3 unit which works perfectly well, to a slightly faster unit that does not do any of the things they are used to, such as OBD and root permissions.

If the factory releases the decryption method for the system image, and someone roots the device, sales will increase, especially when custom ROMs start to appear with tweaks and fixes.

---------- Post added at 06:18 PM ---------- Previous post was at 06:15 PM ----------

I only read some of the post briefly, and it mentioned opening with 7zip, I have tried WinRAR, but no success.

I will take a closer look at the posts today and see what I can do.

Unfortunately I do think the files are actually encrypted, rather than just a different file system, but we can still hope for the best.
[Android Head-Units] sciallo:
Try skipping the unzipping it looks like the ones they're working with come in a single zipped file...
[Android Head-Units] KID52:
My mistake, didn't really read it too well as I said.

Just tried the SGS2toEXT4 Utility, but no luck, just sits in an infinite loop doing nothing.
[Android Head-Units] KID52:
I installed the other firmware today, it appears to be a slightly newer version than the one from Peter Chan, but the default applications have reverted back from the red theme. The only other difference I found was that the newer version came with the "APK Installer" app, but this function was in the settings menu anyway.

Peter Chan Firmware v2.6.40

Other Firmware v2.6.60
[Android Head-Units] chris.r.r:
Peter Chan told me that their factory liked the old UI more, so they reverted it. In my opinion the new UI (at least what I saw in Kid52's video) looks much more modern.
[Android Head-Units] Orisai:
They seem to be encripted using Windows EFS encryption. I've opened the zip file with WinRAR and their names appear in green, which is the color for files with the Encrypted attribute in Windows Explorer.
